Hope you are OK with me chopping to the part of your post I specifically wished to comment.
I found this particular sentiment is not accurate. First many here have been drawn here, if by SLEUTHERS you refer to members of Websleuths, because of a personal event which occurred in their lives. That event has made them hypersensitive to particular events like missing persons. The aim is not some sort of glory seeking, the aim is more fellowship and a genuine desire to help.
Are you saying LE solved Mollie's case 'by themselves"? I would like how if that is what you meant how you got there.
First - We don't know who found Mollie do we?
Second - The media, Crimestoppers, and the family's efforts all were occurring in concert with LE's efforts I find it way too early to draw such a conclusion.
Of course this is all JMOO.
